Check the operation of the overpressure valve if fitted to the vehicle, run test 6 Incorrect operation of the
overpressure valve.
In the event of rail overpressure:
Check that the injectors are operating correctly (see Component test, Test 1, Injector Test).
Check that the rail pressure sensor is operating correctly using command AC011 Rail pressure regulator.
Display parameter PR038 Rail pressure, and refer to the conformity check to check the operating values.
If these checks do not indicate any abnormality and if the fault is still present, replace the injection pump.
in the event of rail underpressure:
Check that the rail pressure sensor is operating correctly using command AC011 Rail pressure regulator.
Display parameter PR038 Rail pressure, and refer to the conformity check to check the operating values.
Check the low pressure diesel circuit priming.
Check the conformity of the diesel filter connections.
Check the condition of the filter (clogging and water saturation).
Check that there are no air bubbles between the filter and the high pressure pump.
Check the low and high pressure diesel fuel circuit sealing (visual inspections, odour, etc.): pump housing,
pressure relief valve, pipes, rail and injector unions, injector wells, etc.
Check that the injectors are operating correctly (see Component test, Test 1, Injector Test).
Carry out the necessary operations.
If the fault is still present, replace the injection pump.
If the fault is still present, replace the injection pump.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– replacing injector(s),
– replacing the injection computer.
Special notes:
If the fault is present:
– the engine speed is limited,
– the level 1 warning light is lit.
1.DEF
NOTESNone.
Program the injector codes using command SC002 Enter injector codes.
Carry out the procedure described in the Interpretation of commands section.
If the fault is still present, after the ignition is switched off and dialogue is established, contact the Techline.
2.DEF
NOTESThis fault appears on any blank computer (new or
recently reprogrammed).
WARNING
A computer without the IMA option can be replaced by a computer with this option. The codes are not
saved during command SC003 Save computer data.
In this case, status ET104 Injector code use changes to YES or FAULTY, fault DF276 will be present, and
the engine will operate in defect mode.
– Program the injector codes using:
command SC002 Enter injector codes, (follow the procedure described in the Interpretation of commands
section).
– After the codes have been entered:
– switch off the ignition,
– wait until power latch closes down and then switch the ignition back on,
– establish dialogue and clear the fault memory,
– end of operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

INJECTOR CODE USE
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
Status ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
– when one or more injectors is replaced,
– when the injection computer is replaced,
– when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
Injector code programming will be present, and the engine will operate in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in
the interpretation of this command.
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction).
WARNING
A computer without the IMA option can be replaced by a computer with this option.
In this scenario status ET104 changes to YES after replacing the computer.
Fault DF276 Injector code programming will be present and the engine will operate
in defect mode.
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

RAIL PRESSURE
NOTESPerform this fault finding procedure:
– after the interpretation of fault DF053 Rail pressure regulation function,
– after an inconsistency for PR038 noted in the Parameters menu,
– after the interpretation of the fault finding procedure for AC011 Rail pressure
regulator,
– following a customer complaint (starting faults, poor performance, stalling, etc.).
Check the continuity and the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track G3Track 2 of the rail pressure sensor connector
Injection computer brown 48-track
connector B, track A4Track 3 of the rail pressure sensor connector
Injection computer, brown 48-track connector
B, track C4Track 1 of the rail pressure sensor connector
If all these connections are correct, check for fuel pressure sensor power supply:
+ 5 V Track 3 of the rail pressure sensor connector
Earth Track 1 of the rail pressure sensor connector
Repair if necessary.
Check the sealing of the low and high-pressure diesel circuits (visual inspections, odour) pump housing,
overpressure valve, pipes, rail and injector unions, injector wells, etc.
If all of the previous checks are correct, switch the ignition on, wait for more than 1 minute and display PR038 Rail
pressure.
If the value is less than 50 bar, the rail pressure sensor is correct. If it is greater than this value, replace the rail
pressure sensor and tighten it to 35 ± 5 Nm.
AFTER REPAIRRepeat the conformity check from the start.
